It’s the first time back at work for cardiologist Conrad Murray, who was Michael Jackson’s personal physician and was with the singer when he died June 25.

Dr. Conrad Murray arrived at the Armstrong Medical Clinic and was greeted by a couple patients and the pastor of his church. He didn't speak with reporters before entering the clinic, but a spokeswoman for his attorney said Murray was looking forward to getting back to work and seeing patients.

He has told police that he gave Jackson a powerful anesthetic to help him sleep.

Murray did not speak with reporters who had gathered at the Armstrong Medical Clinic on Monday. But a spokesman for his attorney said that Murray is looking forward to getting back to work.

Murray, who lives in Las Vegas, has not been charged with a crime.

His attorney, Edward Chernoff, said Murray has not been able to earn a living since Jackson's death.

Authorities searched Murray's Houston clinic and a rented storage unit on July 22 and conducted searches later at Murray's home and office in Las Vegas, at properties in Los Angeles and at a Las Vegas pharmacy where police say Murray bought five 100-milliliter bottles of propofol.

Chernoff said Murray has been followed and threatened since Jackson died and felt he had to close his Las Vegas office because patients were being harassed as they came and went. Chernoff said Murray will eventually reopen that office.
